The Peabody Corporation manufactured the EZ-Pack rear loader. While I do not have any history or technical specs at this time, I am pleased to bring to you some good photos. The town of Junior, WV uses two Peabody EZ-Packs, and I got handy with the camera.
The orange cab truck actually came from Philippi, evidenced by the seal on the door the nearest city, with a population of about 10,000. Junior is probably only about 1,000, so two trucks is more than enough to do the job. On the bottom left side at the front of the body appears the manufacturers inspection plate which shows a date of 1979.
The rear hopper with the compactor mechanism is the part we want to look at next.
As you can imagine, the photo actually shows the stage between steps 2 & 3.
The compactor mechanism consists of an upper packing panel and lower sweeping blade hinged together like on most rear loaders. However, unlike the most common arrangement as on the Cobey Rear Loader, the hydraulic cylinders that operate the sweeper are not attached in-line with the packing panel. Instead, they are attached to each side of the hopper and are free to rotate about a pivot point. Here's how this works, once the compaction cycle begins.
- The sweeper cylinders retract, which opens up the sweeper blade.
- The packing panel cylinders extend which brings the panel down, and sweeper blade towards the edge of the tailgate, about a foot higher than shown in the photo. You can also visualize that the sweeper cylinder must pivot (rotate about the fixed point on the hopper) in order to accomodate the downward motion of the packing panel.
- The sweeper cylinder extends, which pushes the sweeper blade in, scooping out the contents of the hopper.
- The packing panel cylinders retract, lifting the entire mechanism, and therefore the scooped trash into the truck, packing the load. Again, you will note the sweeper blade cylinders now must pivot in the opposite direction to accomodate the upward motion of the packing panel.
Here we see the hopper full of old tires. I can imagine that would take several compacting cycles to consume all of them. Let's hope that doesn't jam the compacting mechanism.
